【摘要】 ＣＡＤ编程中经常遇到各种数表的自动查找问题。本文以ＡｕｔｏＣＡＤ环境下ＡＤＳ编程为例，叙述了多变量数表的查找方法，指出了用数据文件法组织数据具有程序简洁、数表直观从而易于输入和核对数据的优点。文中给出了用数据文件法查找双变量数表的ｃ语言子函数，这种方法同样也适用于其他高级语言的编程。更多还原

【Abstract】 it is a common problem to look up various tables in CAD. A ``data file method" for lookingup multivariable tables in AutoCAD ADS programming is described and the corresponding program ofC func-tion for looking up data tables with two variables is given. The programming procedure can be Simplified andthe data input and its verification become easier by using this method.更多还原
